With the ARIS TACOMAT we offer a mains water Topup unit of the new generation. In addition to its main function the ARIS TACOMAT, equipped with the TACOMAT SECURITY LOGIC, offers a significantly enhanced range of services. Thus we guarantee a continued secure supply and optimal use of rainwater. Once the cistern is empty, the ARIS TACOMAT receives a control signal and switches to potable water. The pump now sucks water from the ARIS TACOMAT, so the security of supply is ensured. The replenishment takes place directly on the ARIS TACOMAT without refilling the cistern first.
